HC3-HPL-AC120V-F Equivalent & Substitute Parts

Part Overview

The HC3-HPL-AC120V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a 3PDT (3 Form C) contact configuration with a 120VAC coil. This through-hole mounted relay is designed for applications requiring multiple independent switching circuits with a 7A contact rating at 250VAC maximum switching voltage. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and redesign applications where continued functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HC3-HPL-AC120V-F is determined by the following critical parameters:

Primary Compatibility Criteria:

• Contact form must be 3PDT (3 Form C) to maintain circuit switching architecture
• Coil voltage must be compatible with 120VAC nominal supply (acceptable range: 115VAC–120VAC)
• Contact rating must meet or exceed 7A minimum current requirement
• Switching voltage rating must support 250VAC or higher
• Mounting type must be through-hole to ensure PCB compatibility
• Termination style must be PC pin for direct board integration
• Coil type must be non-latching for identical operational behavior

The PT371615 from TE Connectivity Potter & Brumfield Relays meets these substitution criteria with compatible electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The PT371615 is a suitable substitute for the HC3-HPL-AC120V-F based on the following engineering factors:

Electrical Compatibility: The PT371615 operates at 115VAC, which is within acceptable tolerance of the original 120VAC specification. The substitute provides superior contact rating (10A versus 7A) and switching voltage capability (400VAC versus 250VAC), offering enhanced performance margins for the application.

Mechanical Compatibility: Both relays feature identical 3PDT contact configuration, through-hole mounting, and PC pin termination, ensuring direct PCB compatibility without layout modifications.

Product Status & Compliance: The PT371615 is an active product with ROHS3 compliance and REACH unaffected status, providing long-term availability and regulatory alignment. The original HC3-HPL-AC120V-F is obsolete, making the PT371615 the appropriate choice for new designs and ongoing system support.

Environmental Performance: The PT371615 supports an extended operating temperature range (-40°C to 70°C) compared to the original (-50°C to 60°C), providing broader environmental coverage for most industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the PT371615 directly replace the HC3-HPL-AC120V-F without PCB modifications?

A: Yes. Both relays share identical through-hole mounting and PC pin termination specifications, allowing direct substitution without PCB layout changes.

Q: Is the 115VAC coil voltage of the PT371615 compatible with a 120VAC supply?

A: Yes. The 115VAC coil voltage is within standard industrial tolerance for 120VAC nominal supplies. The PT371615 must operate voltage of 92VAC and must release voltage of 34.5VAC confirm functional operation across the expected supply range.

Q: What are the key differences between these two relays?

A: The PT371615 provides higher contact current rating (10A versus 7A), higher maximum switching voltage (400VAC versus 250VAC), extended operating temperature range (-40°C to 70°C versus -50°C to 60°C), and active product status with ROHS3 compliance. The original HC3-HPL-AC120V-F is obsolete.

Q: Are there any contact material differences that affect application suitability?

A: The HC3-HPL-AC120V-F uses silver alloy cadmium-free contacts, while the PT371615 uses silver nickel (AgNi) contacts. Both are suitable for general purpose switching applications. Contact material selection depends on specific load characteristics and environmental conditions of the application.

Q: What is the moisture sensitivity level for both relays?

A: Both relays have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or use.

Q: Is the PT371615 available in the same packaging as the original?

A: The PT371615 is supplied in bulk packaging. Verify packaging requirements for your specific procurement and assembly processes.
